Hospital infection has become a global public health problem. The strain of anti-disinfectant, same as the antibiotic-resistant strain, will lead to the failure of the disinfection of the hospital, which will cause hospital infection. The bacterial resistance to disinfectants and resistance mechanism is not clear. Most of the studies focused on the cell research, the molecular research, non-physiological mechanism of resistance, in recent years, the selection pressure, outflow pump were studied. Currently, disinfectants abuse, improper handling and inadequate amount of disinfectant were considered as the main cause of the resistance development.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.

OBJECTIVE To investigate and analyze hand carrier state of medical staff in Tianjin and the antibiotic resistance of the pathogens.METHODS Bacteria or pathogens were isolated from the samples using a sterilized cotton swab on the whole hand before hand washing or hand disinfection,and drug sensitivity test was performed.RESULTS In 16.72% of all samples(50/299),there were 64 kinds of bacteria or pathogens isolated.A.baumannii,Staphylococcus aureus and A.lwoffii were the most common bacteria,40.6% resistant to more then 3 kinds of drugs.Four Meticillin-resistant S.aureus(MRSA) strains were detected out.CONCLUSIONS The high rate of hand carrying bacteria and resistance in Tianjin should pay attention to.

Objective To determine the advantages of laparoscopic cholecystectomy (LC) by establishing pneumoperitoneum under direct vision. Methods A 1cm incision was made just below the umbilicus; lifting and cutting out of the peritoneum at the line alba abdominis with direct vision; then a 10mm trocar was inserted into the pneumoperitoneum cavity.Results There were 107 patients underwent LC.Of them, 93 patients suffered from chronic cholecystitis with gallstone, 6 from acute cholecystitis with gallstone, and 8 from cystopolyps. Among them, 16 patients had previous abdominal operations. Two patients with atrophic cholecystitis converted to open cholecystectomy(OC) owing to the unclear bile duct anatomy. The average operation time was 45min. Postoperative complications included pulmonary infection in 3 patients, bile leakage in 1( due to the titanic clip falling off),but no bile duct injury or other severe complications occurred;and no mortality in this series. Conclusions Establishing pneumoperitoneum under direct vision has following advantages:rapid and safe,and favorable to avoid the severe trocar-related complications.

Objective To compare the different front plastic angle with reinforced plastic endotracheal tube guidance by McGrath -5 video laryngoscope for orotracheal intubation in obesity.Methods 1 20 cases with obesity undergoing general anesthesia,ASA gradeⅠ -Ⅲ who planned intubation guidance by McGrath -5 video laryngo-scope,were randomly divided into three group according to different front plastic angle for endotracheal tube:group A (catheter 60°),group B(catheter 75°),C group(catheter 90°),40 cases in each group.General information and air-way evaluation indexes such as Mallampati classification,the degree of open mouth,neck circumference,thyromental distance,atlanto -occipital joint stretch degree preoperatively were recorded.C /L classification with laryngoscopic exposure,the successful rate of first intubation,time of first intubation,cases of second intubation,the incidence of blood stained catheter and postoperative sore throat and hoarseness were recorded also.Results There were no signif-icant differences of patients with general information and airway evaluating indexes such as Mallampati classification, the degree of open mouth,neck circumference,thyromental distance,atlanto -occipital joint stretch degree among three groups(P >0.05).The successful rate of catheter alignment glottal was 97.5% in group B,which was signifi-cantly higher than that of group A(80.0%)and group C(85.0%)(χ2 =8.36,P <0.05).The time of first intuba-tion was 21 (1 0 -65)s in group B,which was significantly shorter than that in group A[30(1 4 -78)s,Z =3.87,P <0.05]and group C[32(9 -80)s,Z =4.32,P <0.05].All patients in three groups had successful intubation firstly or secondly.The incidence rate of blood stained catheter in group B(2.5%)was significantly lower than that in group A(1 0%)and group C(1 5%,P <0.05 ),but there was no significant difference in postoperative sore throat and hoarseness among three groups(P >0.05).Conclusion McGrath -5 video laryngoscope which guided endotracheal tube with front plastic angle at 75°degree has highest success rate of intubation,shortest intubation time,least compli-cation and is suitable for the application of tracheal intubation in obese patients.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis and treatment of primary testicular yolk sac tumor (YST).

METHODSWe studied 8 cases of primary testicular YST by microscopy and immunohistochemistry.

RESULTSThe 8 cases of primary testicular YST, including 2 consultation cases, were confirmed from 1998 to 2013, accounting for 10.7% (8/75) of all the testicular germ cell tumors diagnosed in our hospital. The patients ranged in age from 7 to 43 years, 23.9 years on average. The main clinical manifestation of the patients was painless unilateral testis swelling. Microscopically, reticular tissues, schiller-duvaI (S-D) bodies, and eosin-stain transparent bodies were seen in the tumors. One of the cases was confirmed to be simple YST, while the other 7 mixed YST. AFP was a characteristic immunophenotype marker of the tumors.

CONCLUSIONPrimary testicular YST is a rare malignancyr with poor prognosis. Its diagnosis depends on preoperative AFP test and postoperative pathology. Comprehensive treatment, including orchiectomy, chemotherapy, and radiotherapy, can prolong the survival of the patients.

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.

METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.

RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).

CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.
